BED-SUPPORT FOR HOSPITALS 0R SICK-ROOMS.

Specification of Letters Patent. Patented Sept, 16, 1913 Application filed April 214, 1913. Serial No. 763,464.

To all whom it may concern:

Be it known that I, HENRY IVEIMER, a citizen of the United States, residing at Winona, in the county of Winona and State of Minnesota, have invented certain new and useful Improvements in Bed-Supports for Hospitals or Sick-Rooms, of which the following is a specification.

My invention relates to a bed support for hospitals or the sick room, and has for its object to provide a construction which may take the place of the ordinary springs upon any bed and which will provide means for all desirable adjustments to support the patient in any position which the character of the patients sickness might require.

To this end I provide a base frame and transversely connected spring members upon the frame, and a support sectionally and hingedly connected together, all of which sections are adjustable relative to one another and to the support and yet all of which sections will have the main part thereof supported by said springs whatever the position of adjustment of the sections.

The full objects and advantages of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claims,

In the drawings, illustrating the application of my invention in one form, Figure 1 is a plan view. Fig. 2 is a side elevation and Fig. 3 is a sectional end view.

The base frame comprises side bars 10 and end bars 11 and 12, indicated by dotted lines in Fig. 2, said frame members being rigidly secured together to form a rectangular frame adapted to fit upon the supports of any bed of usual construction. Rigidly secured upon the frame members at their bottoms are a series of pairs of strong compression springs 13, 14, 15 and 16, respectively. The springs 15 are rigidly connected by means of a fixed crossbar 17 which is securedto the tops of'the springs 15. Each of the pairs of sprin s13, 14- and 16, respectively, are-'connecte transversely by metal crossbars 18, 19 and 20. A head frame comprising side members 21 and 22 and a top crossbar 23, is hingedly connected at the .ends of the .members21 and 22 with the crossbar 17, and when in horizontal posi tion rests at the said ends of said side members upon said crossbar .17, and at its other end upon the spring 16. Hingedly connect-v ed at their ends to frame members 21 and 22 are two. short frame sections 24 and 25, and hingedly connected to the ends of sections 24 and 25 are the ends of side frame members 26 and 27. As best shown in Fig. 1, the respective ends of side members 22, 24 and 26 on one side and the ends of side members 21, 25 and 27 on the other side are cut to a point adjacent the hinge, as indicated at 28, so that all of said side frame members may rest upon the respective sets of springs along the side of the base frame, and will then be in a horizontal plane while permitting relative adjustment of said frame members in opposite directions.

The outer ends of the side frame members 26 and 27 rest upon the springs 13 and have secured thereto and extending inwardly to a point adjacent one another arms 29 and 30, respectively, the said arms being rigidly secured to and in the plane of the side frame members 26 and 27. The arms 29 and 30 each have secured to the under side of the inner ends thereof longitudinal strips 31 and 32, respectively, and said strips are in turn secured to transverse members 33 and 34 which are fastened at their ends to the inner ends of side members 26 and 27. The bars 33 and 34 rest upon the springs 14 and the crossbar 19 connecting said springs, and the ends of longitudinal bars 32 rest upon a depression 35 formed in crossbar 18. There is thus provided a pair sitioned beneath the longitudinal members 26 and 31 while shaft 37 has a similar pair of arms 40 located beneath longitudinal frame members 27 and 32. j

A keeper 41 on the lower side of the frame member 26 extends through the loop of arm '39 and holds the. same in proper position relative to frame member 26, a similar. keeper 42 being secured to the under side of frame member 27 and passing through loop of arm 40. Upon the under sides of frame members 26 and 31, and 27 and 32 are formed a series of notches 43 with which the respective sets of arms 39 and 40 are adapted to engage. When said arms engage in said notches the arms will operate to hold the respective frame systems in a more or less inclined position, as indicated by dotted lines in Fig. 2. Each of the shafts 36 and 37 has its extended ends formed for receiving a square socket in a removable crank handle 44, by means of which one or both of said shafts 36 and 37 may be turned to the extent desired to swing arms 39 or arms 40 upwardly to raise the respective frame systems so as to give them the desired angle.

Beneath the short side frame sections a shaft 45 is journaled in upstanding ears 46 on the arm frame pieces 10. The shaft 45 is provided with a pair of arms 47 formed as loops similar to the arms 39 and 40 on shafts 36 and 37. These loops come beneath the short side frame sections 24 and 25 and are held in position by means of keepers 48 secured to the under side of sections 24 and 25. Ends of arms 47 are adaptsection 2 2 will be supported directly upon the longitudinal frame members 10 through ed to engage in notches 49 formed on the lower side of short sections 24 and 25 by which, as shown in Fig. 2, the said short sections are held in any desired position of angular adjustment relative to the frame members 21 and 22. The extended ends of shaft 45 are adapted to fit in the socket formed on the crank handle 44.

The head section of the spring formed by side members 21 and 22 and cross member 23 is held in desired positions of adjustment by means of arms 50 and 51 pivotally secured, as indicated at 52, to the under side of crossbar 23, and pivotally secured at their other ends to a shaft 53 which has thereon spur gears 54 meshing with and supported by racks 55 formed on the inner sides of frame members 10. The end of shaft 53 is adapted to fit within the socket of crank handle 44. By means of crank handle 44 the shaft 53 may be rotated, thus rotating gears 54 upon the racks 55, which will result in raising the frame members 21 and 22 to any position of longitudinal adjustment with respect to the other longitudinal frame members. The lifting of the device by this means, while positive in its action, will be absolutely without shock or jar, and although the outer end of the back the gears 54 and racks55, the lower end of sald head section will be supported upon the springs 15 Which will, in connection with the movable character of its support upon the links 51, make said back rest very resilient and comfortable for the patient. The gears 54 are held in any position of adjustment to which they may be brought by means of 2.

pawl or pawls 56 engageable in ratchet segments 57 formed on the top of side members 10. To form the direct support for the mattress a canvas may be secured by means of hooks 58 on the bars 33 and 34, said canvas passing over the end bar 23 and being secured to a roller 59 by means of which the canvas may, if desired, be tightened when thehead frame is in its elevated position, mattress sections corresponding to the different frame sections shown may be laid thereon and upon this canvas.

The operation of my improved spring has been fully given in connection with the de tailed description of the same. By means of it the patient may be kept in a horizontal position or with the head raised to any desired extent; also the legs may be independently placed at any angle desired either up or down with respect to the central sup porting portion of the bed and at all times the patient will be supported upon the springs.

The simplicity and cheapness of my adjustable bed are apparent.

My adjustable bed springs may be made sufficiently economical so that the same may be used in the homes'of persons of moderate circumstances who could not afford to purchase the complete and complicated hospital beds now on the market.
